[Ubuntu 22.04] "Oh no" screen + black screen on VNC viewer

[s1s1fo]

Ok

[dcommander]

Are you intending to run GNOME as a window manager? That is the default in TurboVNC if you don't specify a window manager.

[dcommander]

You need to pass -wm xfce, not -wm xfce4. https://turbovnc.org/Documentation/Compatibility30

[dcommander]

Ouch. Can you obtain a stack trace from the Xvnc process?

[dcommander]

NOTE: It's not clear from the server output whether Xvnc or Xfce is crashing. The stack trace obviously wouldn't be relevant if the segfault is occurring in Xfce.

[dcommander]

I don't have the cycles to provide free personalized support, particularly for tasks like obtaining a stack trace that are outside of the purview of TurboVNC. All I can tell you is that I successfully started TurboVNC with Xfce in my own Ubuntu 22.04 installation less than an hour ago, so I'm not sure why it isn't working for you. If it's a legitimate bug in TurboVNC, then I'm happy to fix it, but I can't fix it until I can reproduce it.
